Tesla Fullscreen Jump

The Tesla browser automatically enters "Theater Mode" when accessing certain video websites, which involves dimming the interior lights and displaying the browser in full screen. For the Chinese mainland version of Tesla, Tencent Video is one of these video websites. If you then navigate from Tencent Video to a third-party website, "Theater Mode" will not exit.

This is a single-file dark-themed HTML tool that transforms a user-entered URL into a Tencent → 1905 → target redirect chain designed to trigger Tesla Browser fullscreen behavior. The page is minimal: a URL input, a Jump & Fullscreen button, a cache toggle, a compact card-style history, long-press delete for history cards, and a one-click Clear all.

Known / discovered APIs (as used by this tool)

• Tencent video redirect https://v.qq.com/search_redirect.html?url=<ENCODED_1905_URL> (wraps and redirects to a trusted URL)

• 1905 redirect API (trusted by Tencent video) https://www.1905.com/api/redirec.html?redirect_url=<ENCODED_TARGET> (accepts a target URL that must end with ?www.1905.com and — critically — must be a domain homepage form; allowed examples: https://example.com?www.1905.com and https://example.com:1234?www.1905.com. Not allowed: https://example.com/?www.1905.com or https://example.com/somepage?www.1905.com.)

• Combined chain used by this tool

  https://v.qq.com/search_redirect.html?url=<encodeURIComponent(
      https://www.1905.com/api/redirec.html?redirect_url=<encodeURIComponent( <targetHomepage>?www.1905.com )>
  )>
  

The tool preserves the exact redirec.html filename and uses double encoding as shown above.

How it works (operation principle)

1. User input — any string that looks like a URL or domain.

2. Normalization — script:

   • Prepends https:// if protocol missing (also handles //).
   • Parses with new URL(...). If parsing fails, shows an error.
   • Strips path, query and hash — keeping only protocol://hostname[:port] (this yields a homepage).

3. Build inner target for 1905 — append ?www.1905.com to the normalized homepage:

   https://example.com?www.1905.com
   

4. Encode & wrap:

   • encodeURIComponent the inner target and append to https://www.1905.com/api/redirec.html?redirect_url=
   • encodeURIComponent the whole 1905 URL and append to https://v.qq.com/search_redirect.html?url=

5. Navigate — script sets window.location.href to the final URL to perform the redirect chain (this is what triggers Tesla Browser’s fullscreen behavior, assuming the browser responds to v.qq.com → 1905 chain).

6. History (optional) — when cache toggle is ON, the normalized homepage (protocol + host + optional port) is saved into localStorage and shown as a compact clickable card:

   • Click a card → immediate jump (no intermediate fill).
   • Long-press a card (0.75 s) → delete that history entry (long-press suppresses click so no accidental navigation).
   • “Clear all” button clears local history after confirmation.
   • Max stored items: 12.

Usage

1. Save the index.html file and then deploy it on your self-hosted server or other static page hosting service. Alternatively, you can use the URL automatically generated by GitHub Pages: https://fullscreen.wcy.one.
2. Enter any URL or domain in the input box (examples: example.com, https://example.com/path, example.com:1234).
3. Click Jump & Fullscreen — the tool normalizes and navigates through the Tencent → 1905 → target chain.
4. Toggle cache on/off in the top-right to enable/disable saving normalized homepages.
5. Use history cards to jump directly or long-press (0.75s) to remove a card. Use Clear all to remove entire history.

Important details & examples

• Normalization examples

  • Input example.com/some/page → normalized to https://example.com
  • Input http://example.com:1234/path → normalized to http://example.com:1234 (port preserved)

• Final URL example (for https://example.com):

  inner target:      https://example.com?www.1905.com
  1905 URL:          https://www.1905.com/api/redirec.html?redirect_url=https%3A%2F%2Fexample.com%3Fwww.1905.com
  final (v.qq.com):  https://v.qq.com/search_redirect.html?url=https%3A%2F%2Fwww.1905.com%2Fapi%2Fredirec.html%3Fredirect_url%3Dhttps%253A%252F%252Fexample.com%253Fwww.1905.com
  

• Long-press delete: 750 ms (both mouse and touch). If long-press deletion occurs, subsequent click will not trigger navigation for that event.

---

Configuration (constants inside the HTML)

• TENCENT: Tencent redirect prefix (https://v.qq.com/search_redirect.html?url=)
• SITE1905: 1905 API prefix (https://www.1905.com/api/redirec.html?redirect_url=)
• STORAGE_KEY: "tesla_jump_history_v1"
• MAX_HISTORY: 12
• LONGPRESS_MS: 750 (milliseconds)

You can edit these directly in the HTML file if you need different endpoints, a different storage key, or different time/limits.

Limitations & compatibility

• Due to regulations and safety concerns, the Tesla browser is designed to only activate "Theater Mode" when the vehicle is in "Park" (P) gear; therefore, this tool is only available when the vehicle is in "P" gear.
• The tool only constructs and navigates to the combined redirect URL. Whether the Tesla Browser actually enters fullscreen depends on the browser and the external services (v.qq.com and www.1905.com) continuing to accept and handle redirect patterns as described.
• The 1905 endpoint used here only accepts homepage-style targets that end with ?www.1905.com. Targets containing a path, trailing slash before the ?, or extra path segments will not be accepted by that service per your original description.
• The page requires JavaScript and access to localStorage for history.
• This tool performs no server-side requests other than navigation initiated by the browser when the final URL is loaded.

---

Security & privacy notes

• The tool stores only normalized homepage strings in localStorage (if cache is enabled). No telemetry or external logging is performed by the script.
• Do not input credentials or sensitive query strings — normalization strips path/query but you should avoid putting secrets in the input.
• Navigation to the final URL will contact external domains (v.qq.com and www.1905.com) as part of the intended redirect flow.
